Exam 6: Experimentation and Causal Research

The process of manipulating one or more independent variables and measuring their effect on one or more dependent variables while controlling for the extraneous variables is called a(n)________.

A laboratory environment involves measurement of behavior, attitudes, or perceptions in the environment in which they occur.

In the virtual world, it is more complex but much less costly to manipulate the independent variable and control for mediating variables than it is in the real world.

A static group involves a prior measurement of the test units.

The random group is a preexperimental design in which a group of test units is measured before and after exposure to the treatment.

The process of manipulating one or more independent variables and measuring their effect on one or more dependent variables while controlling for the extraneous variables is called an experiment.

Variables other than the independent variables that influence the response of the test units are called ________.

Concomitant ________ occurs when the presumed cause and presumed effect are both present and both vary in a manner predicted by the researcher's hypothesis.

________ is an application of a controlled experiment done in limited, but carefully selected, test markets.

Concomitant variation occurs when the presumed cause and presumed effect are both present and both vary in a manner predicted by the researcher's hypothesis.

Individuals, organizations, or other entities whose response to independent variables or treatments is being studied are called test units.

An experimental design in which the test units are assigned randomly and the experimental group is exposed to the treatment but the control group is not, and no pretest measure is taken is called the ________.

According to the text, experiments can be described in terms of interdependent variables.

With experimental designs, it is possible to control for some of the extraneous variables.

According to the text, a(n)________ is the group exposed to the manipulated independent variable.

Which of the following is NOT one of the three types of preexperimental designs?

A(n)________ is a statistical experimental design used to measure the effects of two or more independent variables at various levels and to allow for interactions between variables.

________ allow for the statistical control and analysis of external variables.

True experimental designs include the ________ and ________.

All of the following are good examples of test units EXCEPT ________.
